The 50-200 was always one of my favorites from the Oly kit. I switched to Nikon a few years ago, but that lens is one I held on to. Really versatile and quite sharp. it can focus quite close and does well with flowers and the like.

The other lens that I loved, and still kept with my old Oly body was the 50 f2 macro. You also have the EC-20 teleconverter, which works well with the 50 f2. Yep, I kept that teleconverter too. The pair allows life size 1:1 macro and also has great image quality for portraits. The 50 f2 isn't the fastest focus lens, and can be a bit frustrating in that area, but oh my how sharp that lens can be!!!

I sold thousands of dollars of Oly kit, but those I kept. Those lenses are outstanding.
